Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970.

    Epidemiology and management of early blight of tomato incited by Alternaria solani
    (CCSHAU, 2018) Ravinder; Narender Singh
    Early blight disease caused by Alternaria solani is one of the most important fungal diseases of tomato (Lycopersicum esculentum). Keeping in view the enormous loss caused by the pathogen, the present investigation was carried out to study the early blight disease progression in relation to weather parameters and its management by using the plant extracts, bio-agents and fungicides under both in vitro and field conditions during Rabi season, 2017-18 at CCS HAU, Hisar. Survey was conducted in eight villages of two districts (Bhiwani and Hisar) in Haryana and minimum per cent disease intensity was recorded in village Saral of Bhiwani district. The epidemiological study revealed that early sown crop was least affected by the early blight disease compared to the timely and late sown crop. The per cent disease intensity increased with the increased age of the plant. . Mancozeb (75% WP) and hexaconazole and zineb (72% WP) were found to be most effective among the fungicides under in vitro condition. Two plants extract (neem leaf extract and combination of garlic clove and green chili extract) and a bio-agent (Trichoderma viride) was also found effective in inhibiting the mycelial growth of A. solani among the plant extracts and bioagents, respectively. In field conditions, mancozeb 75% WP was found to be most effective in reducing the early blight disease intensity and increasing the fruits yield of tomato crop.
